Abstract
During the ongoing evolution of energy systems toward increasingly flexible, resilient, and digitalized distribution systems, many issues need to be developed. In general, a holistic multi-level systemic view is required on the future enabling technologies, control and management methods, operation and planning principles, regulation as well as market and business models. Increasing integration of intermittent renewable generation and electric vehicles, as well as industry electrification during the evolution, requires a huge amount of flexibility services at multiple time scales and from different voltage levels, resources, and sectors. Active use of distribution network-connected flexible energy resources for flexibility services provision through new marketplaces will also be needed. Therefore, increased collaboration between system operators in operation and planning of the future power system will also become essential during the evolution. In addition, use of integrated cyber-secure, resilient, cost-efficient, and advanced communication technologies and solutions will be of key importance. This paper describes a potential three-stage evolution path toward fully flexible, resilient, and digitalized electricity distribution networks. A special focus of this paper is the evolution and development of adaptive control and management methods as well as compatible collaborative market schemes that can enable the improved provision of flexibility services by distribution network-connected flexible energy resources for local (distribution system operator) and system-wide (transmission system operator) needs.
Highlights
Energy systems are changing due to global drivers related to climate change and environmental issues as well as due to the increasing dependency on electricity
The target of these methods is to maximize the availability of all distribution network-connected flexibilities for different distribution system (DSO) and TSO flexibility needs through future market schemes (Section 4)
The target of these new adaptive control and management methods is to maximize the availability of all LV network-connected flexibilities for different DSO and TSO needs during the evolution (Table 1)
Summary
Energy systems are changing due to global drivers related to climate change and environmental issues as well as due to the increasing dependency on electricity. A holistic multi-level systemic view is required on the future enabling technologies [1,2,3], control and management methods, operation and planning principles, regulation as well as market and business models In this way, the whole energy system costs are minimized, and the collaborative societal and customer value is maximized during the energy system evolution. The target of these methods is to maximize the availability of all distribution network-connected flexibilities for different DSO and TSO flexibility needs through future market schemes (Section 4).
